Comprehensive Digital Twin
ed optimizations to reduce cabin noise.
This process significantly improved the
NVH performance of the vehicle quickly
and for relatively low cost.
With this success in hand, BYD is now
focused on moving from a process of
benchmarking and troubleshooting to
an integrated, model-based approach.
The new process will enable BYD engineers
to account for NVH requirements
early in product development.
As this process connects with other digital
solutions used by the automaker, it
will ensure issues can be resolved and
performance optimized using the comprehensive
digital twin of the vehicle,
well before any physical prototypes are
produced.

Digitalization Delivers Results
Through a holistic digitalization of
product development and manufacturing
processes, BYD has realized the following
outcomes:
* 95 percent improvement in the accuracy
of design data
* connection of product development,
including software, and manufacturing
through a robust lifecycle management
data backbone
* implementation of a model-based electrical
and electronic (E/E) and software
design platform

and testing into manufacturing. (Image: Shutterstock/Jenson)
models and advanced features to deliver
on their global strategic plan. While
focusing on innovation, the automaker
must also reduce its vehicle development
cycle and improve quality to maintain
brand reputation and improve its
footing in a highly competitive market
both at home and abroad.
BYD's challenges are reflective of the
pressures felt by many companies as
they assess the modern industrial landscape.
Several pressures have increased
in recent years across industries, including
widespread workforce shortages
across many roles, increasing costs for
companies and consumers, and swelling
demand for sustainable products and
business practices. With products getting
smarter and more complex, companies
are attempting to produce sophisticated,
sustainable products while
at relative deficit of engineering and
technical talent.

BYD has chosen to address these
challenges by deploying advanced
digital tools and solutions across multiple
phases of vehicle development,
engineering, and production. These
solutions have helped the automaker
to establish traceability throughout the
vehicle design, simulation, testing, and
manufacturing processes. And as software
and electronics components continue
to grow in importance to modern
vehicle functionality, BYD has adopted
solutions to the same effect in managing
its electrical, electronic, and software
development.
For example, BYD is leveraging digitalization
to evolve its approach to noise-vibration-and-harshness
(NVH), a key
facet of the customer experience. As a
first step, BYD used advanced simulation
tools to benchmark the NVH performance
of an existing model against the
competition, and then perform targetwww.techbriefs.com

development of a reliable and efficient
vehicle performance and NVH test
solution.
Moreover, the automaker has also reduced
the cycle time for new vehicle development
by 25 percent - from 24 months
to 18 months - providing a crucial competitive
advantage in the tightly contested
hybrid and electric vehicle market.
The comprehensive digital twin is
a powerful tool for companies as they
navigate the pressures, challenges, and
opportunities of the modern industrial
world. By connecting all cross-domain
models and data from across the product
development, manufacturing, and
usage lifecycles, the comprehensive digital
twin forms the foundation for the
digital transformation of a company, empowering
adopters to surge ahead of the
competition as they innovate faster and
more efficiently.
